Convert Bytes to Kilobytes
B to KB · digital storage conversion
What are bytes and kilobytes?
A byte is 8 bits, enough to store one character of text. A kilobyte is 1,000 bytes (decimal), a common unit for small files. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert bytes to kilobytes
1 B = 0.001 KB. To convert, multiply the number of bytes by 0.001. For example, 5 B = 0.005 KB, and 20 B = 0.02 KB. To go the other way, multiply kilobytes by 1,000 (since 1 KB = 1,000 B).

FAQ
What is 1 B in KB?
1 B = 0.001 KB. To convert any amount, multiply the number of bytes by 0.001.
How do I convert kilobytes back to bytes?
Go the other way: 1 KB = 1,000 B, so multiply kilobytes by 1,000 to get bytes.
Is a byte bigger than a kilobyte?
No — 1 B is the smaller unit, equal to 0.001 KB (it takes 1,000 B to make one KB).
Are these digital storage conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
